The "solution" that the Ontario Line came up with is building the stations so deep that this wouldn't be something they'd have to deal with during construction (which leads us to those infamous diagrams where there are a ton of escalators from Queen Line 1 to OL). They've definitely learned their lesson, although I'm not sure they drew the right conclusions.

On the bright side, there's plenty of vertical space left to build an express subway up Yonge street under the existing tunnel!

Metrolinx do like their deep tunnels. The transfers at Pape are going to be interesting as well. And Lawrence East is a joke.

There’s also the small obstacle of having to have emergency exits lighting and ventilation and first responder access for all of the line - including Eglinton-Yonge. Can’t just drive thru hoping that there will not be an incident in that stretch.

Besides, any part of the line that is opened means the contractor gets paid for tht segment. Do we want the contractor to get 90%+ of their pay while the most important segment is unfinished ? Better leverage if the contractor has to get everything done to get paid.

Maybe, the could at least open the section between Mt Dennis and Eg West Stn / Allen Road. All emergency exists would be in place, and the yard connection is there. The payment for that section won't be big enough to make the contractor too complacent.

KEY QUOTE FROM TORONTO STAR ARTICLE

"At a Metrolinx board meeting in February, Andrew Hope said Crosslinx has some work to finish, “most notably at Yonge and Eglinton, which is the flagship station of the line, where there is very good progress happening at the station, but still some utility and road restoration work to happen in that location which we expect to be finished later this year.”"

In essence this line isn't opening until 2024 at the earliest

I was hoping the lesson learned would be to add an extra year to the schedule to account for this type of unknown.

Ford likes to say subways last for centuries: These are terrible transfer points that great-great grandkids will be stuck using. It's damn hard to realign a tunnel even if you're willing to rebuild the station.

To be fair, a shallower tunnel for the OL would have been so expensive that the public never would have accepted it. Because Queen St also has PATH tunnels, tower foundations, etc, that aren't generally the same issue on Eglinton. Ideally we would have just spent the money, but this is Ontario after all.

I don't think that anyone is realistically suggesting that cut-and-cover be used in the core.

But even with TBMs, there was no reason why they couldn't have dug the tunnels shallower and closer to the bottom of the existing Queen (and Osgoode) station(s). They would have still avoided all of those utilities, and would have made the transfers much easier.

Montréal's Metro has its ups and downs, being totally underground. They built the tunnels to use gravity to help accelerate and decelerate at the stations. The tunnels go UP as they approach a station, and go DOWN as they leave a station.

In Toronto, they have used regenerative braking on their subway trains and streetcars for years (and soon light rail vehicles and whatever the Ontario Line trains will be called), by generating electricity as they brake. Same regenerative braking for hybrid buses and automobiles and electric buses and automobiles.

Even with TBMs, the reason why the tunnels are where they are is to put them in the bedrock. Which eliminates the need to underpin the existing stations. Putting them shallower would have cost more as they would have been in looser soil, which would have had a greater impact on the structures above. As I said, we could have done it, but it would have been much more expensive, and Metrolinx is trying to cut costs everywhere they can unfortunately.

I'd much rather we had spent that money, personally.

Water pooling on uneven payment

I wish this was surprising but it has been clear in many places that grading and surfacing was being rushed. Some of the bike lanes are nowhere near flat, there are odd slopes towards the curbs on sidewalks in places, some entrances are completely level with the surroundings (which isn't great for rain and snow melt). I'm just glad that they are validating the build quality before signing off.

The most painful thing about watching this entire Englinton LRT boondoggle unfold, is the fact that we had started construction on a subway for Eglinton, and cancelled it. That's what's killing me the most watching all this. I don't even enjoy following this project anymore.

Cool video of the new platform.

Do we know what the hold up is with this line opening? Eglinton station is almost filled in. Can't they do testing on the line without the station being "ready"?

Nope - from TRCA Flood Plain Map:

Guess we figured what the machinations are here.

If Douggie and his friends can figure out how to make his friends rich developing on the protected Greenbelt they can wave a magic wand and make the flood plan dissolved. If there is money to make it can be done, if there is a will there is a way..

Next thing you know the flood plain is re-asessed and turns out it's no longer a flood plain. Tada you can build all the condos you want.

This Eglinton LRT station is being ripped up before it has even opened. Here’s why​

Has anyone noticed on the orange canopy right above the entrances to crosstown stations that there’s an annoying reflection of the signage above (eg. Leaside) when its lit and seen at eye level? I don’t think its something that could have been anticipated from the design alone, but once you see it, you can’t unsee it. Maybe its nit picking, but I don’t think so… a bit disappointing as I generally like the look of the stations. I will try to post a pic of it tomorrow.
